Change material projection method?
Are you using Blender Render or Cycles Render? (This is shown at the top of the window.)

If you are using Blender, go to the "Textures" tab in properties, select "Projection" in the mapping tab, and change it to how you like. To tile it, change the size property.


If you are using Cycles, open up Node Editing. Link the Image Texture to the Material, link the Mapping Vector to Image Vector, and link The Texture Coordinate to Mapping. (It makes more sense in an image.) Click "Flat" in the Image Texture, and select a projection. Change the "Scale" values in mapping to tile.
